Objective: Ziziphora clinopodioides is an edible medicinal plant belongs to the Labiatae family that widespread all over Iran. It used as culinary and also in cold and cough treatments in Iran. The aim of present work was to evaluate the effect of different timeframes during the hydrodistillation on essential oil composition, antimicrobial and antioxidant activity. Materials and Methods: The essential oil of Z. clinopodiodes was extracted via hydrodistillation with Clevenger apparatus. The fractions of essential oil were captured at 6 times from the beginning of the distillation: (10, 20, 60, 120, 180 and 240 min). The fractions of essential oil were analyzed by GC/MS and their antibacterial, antifungal and antioxidant activities were studied by Disk - well diffusion and DPPH methods respectively. Results: Six distillation times and whole essential oil were captured during the hydrodistillation. Essential oil yield dropped off significantly during distillation progressed (1.0% for 10 min and 0.025 for 240 min). 1,8 Cineol, Isomenthone, Pulegone, Piperitenone and Citronellic acid were major compounds in fractions and they were affected by distillation times. Pulegone was major compound in all of essential oils. In antioxidant activity assay, whole essential oil was stronger than was stronger than positive control and fractions of essential oil, because of higher levels of Isomenthone, Piperitenone and Citronellic acid. Strongest antimicrobial activity against S. aureus, E. coli and C. albicans was observed from 10 min fraction. Conclusion: Our results indicated that distillation time can create essential oils with specific properties and we can achieve to more efficient essential oil in short times.

Objective: In this work, we investigated the chemical composition and the antioxidant and antimicrobial activities of the Algerian Cistus clusii Dunal essential oil. Methods: Cistus clusii essential oil has been extracted using hydrodistillation method and characterized by GC/MS. The antioxidant activity was evaluated by two different methods DPPH free radical scavenging, and β-carotene bleaching test. The antimicrobial activity was carried out using disc diffusion method against reference strains; Pseudomonas aeruginosa (ATCC 27865), Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923), clinical bacterial (Klebsiella pneumoniae, Proteus mirabilis, Staphylococcus aureus) and fungal (Candida albicans) isolates. Results: The chemical profile of the oil showed 31 compounds. This profile was dominated by the presence of monoterpene hydrocarbons (78.4%), oxygenated derivatives (18.8%) and sesquiterpene hydrocarbons as minor constituents of this essential oil (1.9%). The major constituents were Camphene (20.6%), γ-Terpinene (16.5%), Sabinene (12.8%), and Terpineol-4 (13.5%). Other compounds were found in moderately good amounts like α-Terpinene (8.9%), α-Thujene (5.9%), α-Pinene (4.2%), and α- Terpinolene (3.1%). The results of the antimicrobial activity showed that the highest activity was observed against C. albicans and it was higher than positive control Fluconazole. The essential oil exhibited a strong antioxidant activity, especially in the β-carotene system. Conclusion: This study indicates that Cistus clusii essential oil showed potent antioxidant and moderate antimicrobial activities which could be used to explain the use of this species in traditional medicine.

A water-distilled essential oil (EO) from the aerial parts of Pimpinella cypria Boiss. (Apiaceae), an endemic species in northern Cyprus, was analyzed by GC-FID and GC-MS. Forty-five compounds were identified in the oil, which comprised 81.7% of the total composition. The compound classes in the oil were oxygenated sesquiterpenes (33.9%), sesquiterpenes (22.0%), monoterpenes (11.4%), oxygenated monoterpenes (2.6%), and phenylpropanoids (7.5%). The main components of the oil were ( Z)-β-farnesene (6.0%), spathulenol (5.9%), ar-curcumene (4.3%), and 1,5-epoxy-salvial(4)14-ene (3.8%). The P. cypria EO deterred yellow fever mosquitoes (Aedes aegypti) from biting at a concentration of 10 μg/cm2 in in vitro bioassays. The oil was tested for repellency in assays using human volunteers. The oil had a minimum effective dosage (MED) for repellency of 47 ± 41 μg/cm2 against Ae. aegypti, which was less efficacious than the positive control N,N-diethyl-3-methylbenzamide (DEET). In larval bioassays, P. cypria EO showed an LC50 value of 28.3 ppm against 1st instar Ae. aegypti larvae. P. cypria EO demonstrated dose dependent repellency against nymphs of the lone star tick, Amblyomma americanum. Between 45.0% and 85.0% repellency was observed at concentrations ranging from 26 to 208 μg/cm2. However, P. cypria EO was less effective compared with DEET in the tick bioassays. Cytotoxicity assays showed that the P. cypria EO did not exhibit significant effects up to the maximum treatment concentration of 50 μg/mL on HEK293, PC3, U87MG, and MCF cells. P. cypria EO also demonstrated moderate antimicrobial activity against Gram-negative and -positive bacteria with MICs ranging from 15.6 to 62.5 μg/mL, except for Candida albicans, which showed the same MIC value of 7.8 μg/mL as the positive control, flucytosine. This is the first report on the chemical composition of P. cypria EO and its insecticidal, toxicant, cytotoxic, and antimicrobial activity.

Thymus capitatus growing wild in Sardinia showed different essential oil composition if grown surrounding Cagliari than in north Sardinia. Here we verify the composition and antimicrobial activity of the oil to make it suitable for the cosmetic and confectionery industries. With the aim of improving the scent and the antimicrobical activity of T. capitatus essential oil, a hydroformylation reaction was carried out to transform the unsaturated components of the oil into the corresponding aldehydes. The essential oil of T. capitatus exhibited a significant antibacterial activity (MIC 0.125-0.5 mg/mL), and was also found effective on C. albicans (MIC 0.125 mg/mL). After hydroformylation, several new irregular terpenoid aldehydes were detected. The perfume of the new terpenic-like aldehydes is very agreeable and, therefore, the acceptability of the aroma is remarkably improved, but the antimicrobial activity was not increased.

The genus Juniperus L. (Cupressaceae) consists of ca. 67 species and 34 varieties. Juniperus communis L. grows on dry hills or mountainous tracts and is widely distributed in the northern hemisphere. A typical variety J. communis L. var. communis was collected in Deliblatska pescara (Deliblato Sands) and variety J. communis L. var. saxatilis Pall. in Kopaonik Mountain. Needle essential oils were obtained using Clevenger apparatus and analyzed using GC/MS and GC/FID. Antioxidant activity of essential oils was evaluated using DPPH assay. A total of 78 compounds were detected and identified. Both oils are characterized by high abundance of monoterpenes. The main constituents of J. communis var. communis essential oil were sabinene (39.4%), ?-pinene (13.3%), myrcene (4.7%) and terpinen-4-ol (3.7%), while J. communis var. saxatilis essential oil had ?-pinene (34.9%), sabinene (20.3%), ?-3-carene (6.4%) and germacrene B (6.3%) as the most abundant components. DPPH test showed IC50 values 0.66 mg/ml for J. communis var. communis and 0.32 mg/ml for J. communis var. saxatilis. Although antioxidant activity was weaker than used standards (BHT and L-ascorbic acid) it is still significant.
